ANTISMUTTING DEVICE FOR PRINTING MACHINERY.

Specification of Letters Patent.

Application filed July 18, 1907.

To all whom it may concern:

Be it known that I, EDGAR H. CorTRELL, a citizen of the United States,and resident of Stonington, in the county of New London and State ofConnecticut, have invented a new and useful Improvement in AntismuttingDevices for Printing Machinery, of which the followingis aspecification.

The object of this invention is to provide novel mechanism forpreventing smutting of a plurality of printed webs as they are passedthrough a cutting and folding machine, the smut web being delivered fromone roll and wound onto another roll after having been passedsuccessively between each printed web and its former at the same speedas the speed of the printed web.

In the accompanying drawings, Figure 1 is a view in perspective showingso much of a cutting and folding machine as will give a clearunderstanding of the construction, form and arrangement of myimprovement as applied thereto, Fig. 2 is a view in front elevation of aportion of the cutting and fold ing machine, Fig. 3 is a horizontalsection taken in the plane of the line AA of Fig. 2, Fig. 4 is a view inside elevation of a portion of the cutting and folding machine with myimprovement applied thereto, and Fig. 5 is a detail section taken in theplane of the line BB of Fig. 3.

The framing of the cutting and folding machine is denoted by 1. Theprinted web as it is fed to the cutting and folding machine before it isslit, is denoted by 2 and thetwo webs formed by slitting the web as itcomes from the slitting machine, are denoted by 3 and 4 respectively.Two stationary formers 5 and 6 are shown mounted on the framing 1,around which formers the printed webs 3 and 4 are turned. Rolls 7 and 8are mounted in the framing 1, over which the printed web is passed onits way to the formers. A slitter 9 of any well known and approved formis shown in position to slit the printed web as it' comes into thecutting and folding machine, which slitter is shown herein as operatingat the time that the web passes over the roll 8. The printed web 3 afterleaving the former 5, passes around two longitudinally disposedhorizontal upper and lower rolls 10 and 11 mounted in the framing 1. Theprinted web 3 is then led from the roll 11 in a direction at rightangles to the direction of its movement as it enters the cutting andfolding machine.

The printed web 4, after it passes over the former 6, passes around twolongitudinally disposed horizontal upper and lower rolls 12 and 13.After passing around the roll 13, the printed web 4 is led from themachinein a direction at right angles to the direction in which itenters the machine and beneath the web 3.

The smut web, denoted by 14, is delivered from the roll 15 mounted inthe framing 1. From the roll 15, the web passes upwardly over the roll8, between it and the printed web 3. From thence the smut web passesaround the former 5, between it 'and the.

printed web. A longitudinally disposed horizontal roll 16 is locatedadjacent to the printed web lower roll 11, around which roll 16 the smutweb 14 passes. From thence the smut web passesv around a horizontallydisposed turning bar 17 arranged at an angle of forty-five degrees. Thesmut web 14 is then led rearwardly and around a roll 18 mounted insuitable bearings in the framing 1. The smut web is then led upwardlyand again passes around the roll 8 but this time between it and theprinted web 4. From thence the smut web passes around the former 6between it and the printed web 4.

Longitudinally disposed horizontal rolls 19, 20 are mounted in theframing adjacent to the lower printed web roll 13 and the smut web 14passes under the roll 19 and over the roll 20 and from thence on to thesmut web winding roll 21 which is supported on two longitudinallydisposed rolls 22, 23. The winding roll 21 is loosely mounted in theframing so that the said winding roll will at all times rest upon thefriction driving rolls 22, 23.

The mechanism which I have shown for passing the printed webs and smutweb over the formers at the same speed and for winding the smut web onto the winding roll is constructed, arranged and operated as follows. Anupright shaft 24 is driven at the desired speed from the press. Thisshaft has a bevel gear driving connection 25, 26 with the roll 7 overwhich the printed web 2 passes before it is sub-divided. This roll 7 hasa spur gear driving connection 27, 28, 29, with the roll 8 around whichthe smut web 14 passes on its way to the formers. The upright shaft 24also has a bevel gear driving connection 30, 31, with a cross shaft 32which carries the smut web roll 18 hereinbefore referred to. This shaft32 has a spur gear driving connection 33, 34, with a transverse shaft 35mounted in the framing, which shaft in turn has a bevel gear drivingconnection 36, 37 with the lower printedweb roll 13. The roll 13 has aspur gear driving connection 38, 39, 40 with the roll 12. This roll 13also has a spur gear driving connection 38, 39, 41, 42 with the smut webroll 16. This smut web roll 16 has a spur gear driving connection 42,43, with the lower printed web roll '11. This lower printed web roll 11has a spur gear driving connection 43, 44, 45, with the upper printedweb roll 10.

The printed web roll 13 has a spur gear driving connection 46, 47, withthe smut web rolls 19, 20 and the smut web roll 20 has a spur geardriving connection 48, 49 with the roll 22 which in turn has a spur geardriving connection 49, 50, 51 with the roll 23.

From the above descripition it will be seen that a single smut web maybe provided for a plurality of printed webs, which smut .web may beinterposed between each printed web and the former over which it isturned, the smut web being driven at the same speed as the printed websand arranged also'to present a fresh surface to each fresh surface ofthe printed webs. It will also be seen that as soon as the smut web hasbeen wound entirely on to the roll 21, the roll 21 may be used as thesmut web delivery roll and the smut web again run through the machine.Furthermore, the smut web is turned in such a manner after it has passedbetween the printed web 3 and its former that it presents its oppositeface to the printed web 4 when it is passed between it and its former.

That I claim is:

1. In a cutting and folding machine, a plurality of formers, means forpassing a plurality of printed webs over the formers, smut web deliveryand winding rolls and means for passing the smut web from the deliveryroll successively between the formers and the printed webs at the samespeed as the printed welaps and from the last former to the winding ro2.' In a cutting and folding machine, a plurality of formers, means forpassing a plurality of printed webs over the formers, smut web deliveryand Winding rolls, friction driving rolls forming a support for thewinding roll, and means for passing the smut web from the delivery rollsuccessively between the formers and the printed webs at the same speedas the printed webs and from the last former to the winding roll.

3. In a cutting and folding machine, a plurality of formers, means forpassing a plurality of printed webs over the formers, a smut webdelivery roll mounted on an axis transversely of the machine, a smut webwinding roll mounted longitudinally of the machine, a turning bar andmeans for passing the smut web from the delivery roll between one formerand its printed web, thence around the turning bar, thence between asucceeding former and its printed web and from thence to the windingroll.

4. In a cutting and folding machine, a plurality of formers, means forpassing a plurality of printed webs over the formers, a smut webdelivery roll mounted on an aXis transversely of the machine, a smut webwinding roll mounted longitudinally of the machine, friction drivingrolls forming a support for the winding roll, a turning bar and meansfor passing the smut web from the delivery roll between one former andits printed web, thence around the turning bar, thence between asucceeding former and its printed web and thence to the winding roll.

In testimony, that I claim the foregoing as my invention, I have signedmy name in presence of two witnesses, this 9th day of July 1907.
